The present invention relates to a microcapsule containing a glycoprotein derived from plants. Also, the present invention provides a microcapsule having oxidation ability and which is easy to prepare. Through said antioxidant capacity, oxidation and decomposition of an internally contained material can be prevented. According to the microcapsule of the present invention, the active components, in a form which was previously stabilized by a synthetic polymer derived from crude oil or by a surfactant, can be stabilized by naturally derived components. Also, since an organic solvent is not additionally used during the capsule preparation process, the preparation is simple and eco-friendly.
